New medical ultrasound technology rides wave of the future

12.05.2005


A fully digital 4D ultrasound system is set to provide a ‘next generation’ integrated solution for medical imaging applications, allowing practitioners to provide faster treatment and improve therapeutic success rates.



Developed by ADUMS, an IST-funded project that ended in April 2005, the advanced high-quality imaging system will significantly reduce diagnostic time. In addition, the technology uses off-the-shelf computer hardware, making it a much cheaper alternative to expensive, purpose-produced ultrasound machines.

“The whole process of ultrasound devices has been moved away from the traditional hardware and is now implemented in software,” says Dr Georgios Sakas, ADUMS project coordinator. “The hardware of the device creates mechanical waves and receives the echoes. Once the echoes are received, they are converted in digital form and the rest of the processing is performed by software.”


A 4D ultrasound takes multiple images in rapid succession, creating a three-dimensional motion video, which is invaluable for diagnosis purposes.

An important factor in ultrasound image processing is the beamformer, the part of the system that provides the focusing for the ultrasound beam. Dr Stergios Stergiopoulos, president of the Canadian National Medical Technologies, one of the project partners, maintains that even today’s most advanced state-of- the-art medical ultrasound imaging systems suffer from very poor image resolution.

“This is the result of the very small size of deployed arrays of sensors and the distortion effects by the influence of the human body’s non-linear propagation characteristics,” he says. “The ADUMS project technology replaces the beamformer of the ultrasound systems with the adaptive beamforming scheme that has been developed for the sonar array systems of the Canadian Navy. The ADUMS project results demonstrated that the new adaptive beamformer significantly improves, at very low cost, the image resolution capabilities of the ultrasound imaging systems, which will result in better diagnosis.”

Until now, every new generation of the hardware component of ultrasound devices was, effectively, a complete redesign.

“On the other hand, ADUMS technology is based on a complete software approach, using off-the-shelf PC components,” explains Dr Sakas. “Thus, a redesign from scratch will not be necessary and future improvements can be made by extensions of existing software.”

The portability and the low cost of the 4D ultrasound systems allow medical practitioners and family physicians to have ready access to diagnostic imaging systems on a daily basis and will make a valuable contribution in the field of preventive medicine, adds Dr Stergiopoulos.

Consortium partners are currently using the new technology for their businesses and are promoting it to other organisations that use ultrasound technology.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
